I'd say Coach Cal has a pretty good record given what he built at UMass and at Memphis. Particularly, if he brings those three prospects (Wall, Cousins, and Henry) over to Kentucky, you're talking about a legit final-four team next year easily. He's a top-tier recruiter, even if the kids stay for a one-and-done. He has connections with William Wesley.
In any case, he'll done a damn fine job. Guys like Izzo, Williams, Coach K, Pitinio and Donovan aren't going anywhere. Who else would you rather get. It's that situation where the newest contract is the largest. Callipari is a legit top-10 coach, which is good enough to make deep NCAA runs every year. I'm not surprised in the least that he got paid that much.
